So far all of Wii games' reviews have not been very good. The highly enticipated "Red Steel" is receiving mediocore reviews. Another highly anticipated "Legend of Zelda" is getting a good but not great review, it's the same old game.
Wii is a toy, a toy that you will quickly be tired of. I have little doubt that you will be entertained when you tried out the Wii games, but you will also be tired of the games fast. Not to mention the graphical power of Wii is about the same as the old xbox. Another issue with Wii right now is the sensitivity issues. Reviewers have been complaining about the controller sensitivity issues of the controller that many Wii games have.
With that being said, if you are kid or adults who don't play video games often and would like to be able to play games with your kids, Wii might be the more suitable option to you. If you are looking for a console that showcase the technologically advance graphic while featuring high production games that will keep you entertained for a long time, ps3 and xbox360 is the way to go. PS3 also provide many attractive functionalities such as the abilities to play Blu-Ray, music, video, photos, run linux, and allowing custom softwares. I would say ps3 is the best machine in this console war.
